Lap Pace only shows +/- ten second (occasionally five) prediction.

I have had a number of Garmin Watches and with all of them (even the Fenix 3) I was able to reliably run even spits, using the projected lap pace.  Unfortunately, my new Fenix 6 only displays pace in ten second intervals (occasionally a five will show up).  For example, if I am trying to run a 7:37 pace, my watch will show 7:30 or 7:40, which may not sound like a big difference but it is huge over a marathon etc. (difference between success and epic failure).  

I cant believe my $1,000 watch can not track pace as well as my Garmin 235 could.  I have 100% checked that i am using lap pace and not instant pace.  I have tried all three the GPS options and I still cannot get an accurate lap pace.  I also have verified I a not on a power saving setting. 

Any ideas.. anyone else have this issue?
